METHOD AND DEVICE FOR OPERATING A GENERATOR SET, INTERNAL COMBUSTION ENGINE, AND GENERATOR SET COMPRISING THE INTERNAL COMBUSTION ENGINE AND A GENERATOR

A method for operating a generator set includes: operating the generator set in synchronized manner to a power grid, which includes: synchronizing a generator voltage with a grid voltage; matching a generator voltage frequency and/or a generator voltage phase with a grid frequency and/or a grid voltage phase; operating generator set in synchronization mode to synchronize the generator voltage phase with the grid voltage phase; operating an engine in a phase control mode with adjustment of an engine phase to change the generator voltage phase; transmitting the grid voltage phase to a phase regulator; regulating, by the phase regulator, the engine phase to a phase difference, which is created by a difference between the generator voltage phase and the grid voltage phase; and setting a phase parameter formed as the combustion control variable for torque-forming combustion setting of the engine, to adjust the engine phase subject to the phase difference.
